1. What is Gravitational Force At An Angle?

Definition: This calculator computes the component of gravitational force acting along an inclined surface.

Purpose: It helps in physics and engineering problems involving inclined planes, ramps, or any situation where gravity acts at an angle.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ F_{gx} = m \times g \times \sin(\theta) \]

Where:

\( F_{gx} \) — Gravitational force component along the surface (Newtons)
\( m \) — Mass of the object (kilograms)
\( g \) — Acceleration due to gravity (9.81 m/s² on Earth)
\( \theta \) — Angle of inclination (degrees)

Explanation: The formula calculates the component of gravitational force that acts parallel to the inclined surface.

3. Importance of This Calculation

Details: Understanding this force component is crucial for analyzing motion on inclined planes, calculating required friction, and designing ramps or sloped surfaces.

4. Using the Calculator

Tips: Enter the mass in kg, gravity (default 9.81 m/s²), and angle (0-90 degrees). All values must be positive, with angle between 0 and 90 degrees.

5. Frequently Asked Questions (FAQ)

Q1: What happens at 0 degrees?
A: At 0° (flat surface), sin(0)=0, so F_gx=0 - all gravitational force is perpendicular to the surface.

Q2: What happens at 90 degrees?
A: At 90° (vertical), sin(90)=1, so F_gx=mg - the full gravitational force acts downward.

Q3: How does this relate to friction?
A: The perpendicular component (F_gy=mg cosθ) affects normal force and thus friction.

Q4: Can I use this for other planets?
A: Yes, just change the gravity value to that planet's gravitational acceleration.

Q5: What about air resistance?
A: This calculator only considers gravitational force, not other forces like air resistance.
